Title: Differential amplifier circuit
Inventor: YAMAZAKI DAISUKE
IPC: H03F3/34
Filed: 1998-07-10
Abstract: PROBLEM TO BE SOLVED: To provide a circuit configuration by which a sufficient phase margin of a loop gain can be taken in a DC feedback differential amplifier circuit. SOLUTION: A noninverting signal and an inverting signal received respectively from input terminals 1, 2 are given to capacitors 1, 2 respectively, in which DC components of them are eliminated and the resulting signal is given to a DC level generating circuit 3. The DC level generating circuit 3 gives newly a DC component to each signal from which the DC component is eliminated by the capacitors 1, 2, and a low pass filter using the capacitors 1, 2 extracts only the DC voltage. The DC level generating circuit 3 incorporating the low pass filter using the capacitors 1, 2 is configured to be a circuit by which no high-cut frequency is introduced other than the high-cut frequency introduced to the loop gain by the low pass filter. Thus, since only one high-cut frequency is in existence in the loop gain, oscillation of a feedback circuit is prevented.

IPC: G06F11/10
Filed: 1983-10-20
Abstract: A multiprocessor computer system having n parallel-operating computer modules which each include a processor module, a memory module and a data word reconstruction module, wherein each module of said system processes the same piece of data simultaneously and in parallel. The data words are applied to a reducing encoder so that code symbols stored in the relevant computer modules form a code word. The relevant error-correction code has a simultaneous correction capability in at least two code symbols. Each data word reconstruction module receives the entire code word in order to reconstruct the data word therefrom. Each computer module also has an input/output memory module. This module receives a coded data word which is decoded when it is presented again. Decoding is performed so that each bit in the input/output memory is mapped on at the most one bit of the associated memory module.
